To nl] wlw/n it may concern.'

lc it known thatl l, MICHAEL J. OWENS, a citizen of the l'nited Statesof America, residing at Toledo, in thc county of Lucas and Stute ofOhio, have invented certain new and useful Improvements in GlassGathering and Blowing Machines, of which the followingl is aspecification, reference being had therein to the accolnpanyingdrawings.

The invention relates to improvements 1n a glass gathering and blowingmachine and consists in a steadying device for the blank, in theconstruction of such steadying device applied as a bottom for theblank-mold, in the construction of the operating device for the steadyngdevice and also in the construction of the blow-mold and the operatingdevice therefor; all as hereinafter more particularly set forth andpointed ont in the claims.

In the drawings:

Figure 1 is a side elevation of my improved derice, with parts brokenaway,

showing in full lines the position of the y blank-mold, blow-mold andsteadying-device for the bottom, during the charging of the blank-mold,and showing in dotted lines the position of the steadying device afterthe blank-mold is charged;

Fig. 2 is an elevation similar to Fig. 1, showing the blank-mold open,the blank lsuspended from the neck-mold, and the blow-molds moved partlytoward their upper position;

Fig. 3 is a front elevation showing the parts in the position of thefull lines 1n Fig. 1;

Fig. -l is a plan view, partly in section, of the blow-inold slide; andl l Figs. to 11. inclusive, are sec-tional views, more or lessdiagrammatic, showing the various positions of the parts during thefilling of the blank-mold, the cutting-olf of the glass` the blowing ofthe blank, the shifting of the molds, the blowing of the article and theopening of the molds for discharging.

This invention is designed as an improvenient to the so-called Owensbottle machine, which, as ordinarily constructed, consists of a rotarytraveling frame carrying a series of blank-molds successively intooperative relation with a pool of glass, Whereby the blank-mold ischarged through an opening in the lower end by a differential pressureor vacuum; the glass in the blank is then severed from the glass in thetank, to which it is connected by a string or neck;

-the blank is blown in the blank mold; the

knife withdrawn and the lower partof the blank-mold opened, leaving theblank suspendedfrom the neck-mold portion of the blank-mold theblow-mold incloses the blank, the blank is expanded in the blow-mold andthe molds opened to discharge the article therefrom. This general typeof machine is shown in patent to M. J. Owens No. 766,768, issued August2, 1901i, and the patent to lV. oock, No. $70,664:, issued November 12,

This particular mechanism is designed to be applied as an improvement tothe Owens bottle machine shownv in the patent to La France, 1,185,687,June 6, 1916, for which this present construction is particularlyvdesigned to be applied.

I have shown in Fig. 3 a portion,k of the upper portion of the revolvingframe which carries the blank-molds and cut-olf, but I have not deemedit necessary to show herein those parts which actuate the sections ofthe blank-mold and neck-mold, the cut-olf and the air and vacuum valves,as those parts are well-known in the art at the present time and form nopart of my present invention.

A represents the base of the machine, upon which is supported my rotaryframe, B. I have shown at C a. circular rack to which may be applied thedrive pinion for causing the frame B to` turn about its central axisupon the base A. D indicates the body portion of the blank-mold and Ethe neck-mold or neck portion thereof; both being .made in two separablehalves and having means (not shown) y for opening and closing the same,which may be of thel usual construction.A F represents the tank for themolten glass, to which the lower end of the blank-mold is dipped, atwhich time a vacuum is produced therein by suitable valve connections,so as Ito suck the blankinto the mold, as shown in Fig. 5. G representsa core or plunger in the upper end of the blank-mold, to form theinitial blowopening in the blank. H is the-'blow-head below which theblank-mold and neck-mold sections are supported. I is the knifesupported at the lower end of the vertical rockshafl: J, for cutting offthe string 0r neck of glass which is lifted from the molten mass in thetank as the blank-mold. lifts therefrom, as shown in Fig. 6. Heretofore,vin the manufacture of the Owens bottle machine, the knife has beenretained beneath the bottom of the blank during the blowing of theblank, but in this machine, as soon as the cut-off has been effected,the knife is immediately withdrawn, leaving the opening in the lower endo'f the blank-moldl exposed.

Below the blank-mold and secured to the rotary frame B is a laterallyextending bracket, K, to which are secured the cylinders L L', eachhaving a piston, M, M, to which are connected the piston rods N N,extending through suitable stuffing boxes in the upper end.v The upperend4 of the piston rod N is connected to the blow-mold slide, 0, inthetop of a bracket, slidably connected byf suitable guides, P, with thefront of the frame B. The upper end o f the piston rod N has formed uponit a suitable shaped bottom-plate Q. This plate is shaped according tothe particular article which is'to be made in the machine; in this caseit is y shown as convex to make the concave bottom portion of abottle. v

Upon the blow-mold slide O are hinged blow-mold sections R pivoted uponthe pins R. Atthe outer end of the blow-mold slideV O are verticaljournals, S, in which are journaled the shafts S', each having at itsupper end a crank, T, connected by a link, T, withone of the blow-moldsections. At the lower lend and secured .to each of the shafts SVSf arethe gear segments, U, *meshingf with rack-bars, U', which in turn areeach connected to the piston, V, in horizontallyarrang dI cylinders,yV", inthe blow-mold slide'i' v s Suitabley'air connections, a o, at thetop bottom of thecylinders L L, controlled by cain'sl' on" "thestationary frame J about which? the Lframe" Bfrotates, in vithei "wellnknown" manner `of applying 'such""c'arns in A the i machines (such fcams not beir'ig` "here shown) control 'the inlet and; exhaust" of .thevairfabove V'and' below the pistons.

Suitable air pipes c' c" cnnectinto the cylinders V. and are controlled,by'suit-y yable cams (notshown) which are arranged" 'to give vthe propertiming effect to the movement of the parts to be hereinafterdescribed.

rlhe parts being thus constructed, theirv operation is as follows:

1n theJ filling of the blank-mold the parts are in the positionshown yinFig. 1 and a part of the blank-'mold isshown inv/position vin dottedlines in Fig. 1.

for gathering 'the glass and filling the same. VVhelr the blank-mold isilled, as shown in Fig. 5, it is lifted during the travel ,of thelmachine above the surface of` the glass, as

shown in Fig. 6, and the: cut-ofi knife severs the neck 0f glass inthewell-known manner and isfwithdrawn Vand lifted to the position shown atthe left-hand of Fig. 3. The blank- .mold, as is well-known, has acontinuous ltraveling movement, and as it passes beyond the tank air isadmitted to the bottom of the cylinder L and the piston M is lifted,carryingfwith it the bottom-plate Q, which lifts said bottom-plateagainst the bottom of the blank-mold, as shown in Fig. 7 and The plungerG having been withdrawn, air is admitted under pressure and the blank isblown in the blank-mold.

The bottom-plate Q, remains in position and the lower or body portion*4D of the blank-mold is opened, leaving the blank suspended from 'the.neck-mold E, while its lower `end is supported and steadied by thebottom-plate Q, as shown inFig. 8. 'As the body `blank-mold sectionsopen, airis admitted beneath the piston Mfand the blowmold slide Gisraised, carrying with it the blow-mold and `the operatingdevicestherefor, until the blow-mold sections are in contact with the undersideof the'neck-mold E,

as shown in Fig.V 9.

Air isthen admitted to the pipes c behind the pistons V and the racks Uare pushed outward, rocking the gear segments y U, the shafts S', crankarms T and links T',

and closing the'blow-mold about Ithe `lower portion of the blank, to theposition shown inFig.10. v 'l "Air is then admitted into thetop of theblank and it is expanded into the finished article, as shown inl Fig.10. l

The neck-mold sections and blow-mold sections are then opened, as shownin Fig.

tirel rvor nearly eliminated. .By retaining..

the ottoni-plate iii-contact with the' lower end ofthe blank durin'g'thetime that. the blank-moldsV are' opening v'and the blow-e moldsinclosing vthe"blank,\the swinging of the bla-nk due tjo' the vibrationcaused by the travel of, `the machine is ventirely el'imlnated andthepossibilit'y of the blank standing at an angle in the blow-mold,which would cause a defective or inferior bottle, is eliminated.

The use of the vertically rising blow-mold is a more simple and rapidlyoperating device for the blow-mold than has heretofore been used,enabling the machine to be speeded upvso that more bottles per minutewill be produced than by such machines heretofore used. The devices arealso able to operate with less wear than with the devices in which themolds are raised and lowered by running upon cam-ways. The blow-moldbeing held against the neckmold by air pressure maintains a tight jointwithout danger of leakage, and eliminates the necessity of springsheretofore employed for this purpose. By the use of thel'air to closethe blow-molds the use of springs is obviated as there is an air-cushionin case p'articls of glass should get between the mold sections, andthus the danger ofbreakage of the blow-molds or operating parts isgreatly reduced.
